Membership Plugin - 'Add New' membership level not working

Weird... i have setup my membership plugin (vs. 1.0.3) in the plugins directory, activated it.. everything saves, but when I click on 'add new' in edit levels, nothing happens.

Same happens or edit subscriptions.

Would this be something related to my DB?

EDIT: Setup the membership plugin the same way as I set it up in Mu Plugins, it works now.

Please close this thread thanks.
